A voltage measuring apparatus and method are provided, in particular a measuring apparatus (30) and method capable of measuring a traction voltage provided by a traction voltage system to a high voltage device (22) in a vehicle when the traction voltage system (10) is in operation, the measuring apparatus (30) being detachably connected between the traction voltage system (10) and the high voltage device (22), the measuring device (30) comprises: first and second terminals (32a, 32b) configured to receive first and second probes of a voltage measuring instrument; first and second resistors (34a, 34b) arranged to connect each terminal (32a, 32b) to first and second traction voltage conductors (12a-d) of the traction voltage system (10) extending through the measurement device (30) when the measurement device (30) is attached to the traction voltage system (10), wherein the measuring device (30) is configured to be connected to a high voltage interlock loop (HVIL) 18 of the vehicle extending through the measuring device (30) when the measuring device (30) is attached to the traction voltage system (10), such that when the measuring device (30) is detached from the traction voltage system (10), the HVIL (18) is disconnected to deactivate the traction voltage system (10).

    提供了电压测量装置及方法,尤其是能在牵引电压系统(10)处于操作中的情况下测量由牵引电压系统提供给车辆中的高压设备(22)的牵引电压的测量装置(30)和方法,测量装置(30)可拆卸地连接在牵引电压系统(10)与高压设备(22)之间,测量装置(30)包括:被配置为接收电压测量仪的第一和第二探头的第一和第二端子(32a、32b);被布置成在测量装置(30)附接到牵引电压系统(10)时将每个端子(32a、32b)连接到牵引电压系统(10)的延伸穿过测量装置(30)的第一和第二牵引电压导体(12a‑d)的第一和第二电阻器(34a、34b),其中测量装置(30)配置为在测量装置(30)附接到牵引电压系统(10)时连接到车辆的延伸穿过测量装置(30)的高压互锁环路(HVIL)18,使得当测量装置(30)从牵引电压系统(10)拆下时,HVIL(18)断开而使牵引电压系统(10)失效。
